Core Viewpoint - The article addresses public concerns regarding electromagnetic radiation from substations, clarifying that the electromagnetic fields produced are not harmful and are well within safety standards [1][2]. Group 1: Misconceptions about Electromagnetic Radiation - Public misconceptions equate substations and high-voltage lines with harmful electromagnetic radiation, which is a misunderstanding [1]. - The actual concern should be with high-frequency electromagnetic waves, such as X-rays and mobile signals, rather than the low-frequency fields generated by substations [1]. Group 2: Safety Standards and Measurements - The recommended safety standards for electromagnetic fields near residential areas in China are an electric field strength not exceeding 4000 volts/meter and a magnetic induction strength not exceeding 100 microtesla [2]. - Continuous monitoring shows that the electromagnetic field strength at the boundaries of substations is significantly below these national standards, with typical measurements for 110 kV and 220 kV substations being only a few tens of volts/meter and very low magnetic induction [2]. Group 3: Comparative Analysis with Household Appliances - Measurements taken at a 220 kV substation in Wuhan showed electric field strengths between 2.15 volts/meter and 2.20 volts/meter, and magnetic induction strengths between 0.23 microtesla and 0.30 microtesla, indicating a large safety margin compared to national limits [2][3]. - In comparison, common household appliances such as electric shavers, kettles, and hairdryers exhibit higher electric field strengths than those measured near substations, further demonstrating the low risk associated with substations [3].
